Yes, that's my primary purpose for it, Mark. I will use the trailing
read in simple loops, but for situations where the conditioning is
complex, I prefer leading read with ITER. I fogrot an important point.
I don't do DOU condition, I just do a forever loop.
setll (field1: field2) file1r;
dow (1=1);
reade (field1: field2) file1r;
if %eof(file1);
leave;
endif;
if someConditionNotMet;
iter;
endif;
...doStuff
enddo;
I should put in an RFE for a DO opcode that simply loops. I hate
writing (1=1). But that's just me. :)

Roger, Don,
I personally like it, since it's concise and doesn't require an
additional %EOF() test, but it doesn't lend itself to using the ITER
opcode.
